Hitsu's only chance would be releasing bankai immediately, depending on distance he could still lose.
If Hitsu tries to engage in swordplay, well let's just say Zoro won't be as patient as Harribel.
If he stays in the air beyond Zoro's reach and uses that technique then Zoro is essentially helpless. Any other scenario though and I'd give Zoro the majority.
Zoro could always throw his sword while Toshiro is about to do that.
